What about this one . . 15 + 2x ≤ 0

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x,y) coordinate plane?

Angles 1 and 2 are complimentary angles. angle 1 = 52 degrees. what is the measure of angle 2?
